Download Introduction to Whole Numbers and Integers

 Introduction to Whole Numbers and Integers Numbers can be used for many different purposes. The cost of a house is a number that mathematics can be performed on to obtain some new amount. For example: Vendor wants a quick sale, was $500 000, now $495 000. However, some numbers are never used mathematically such as your postcode, your telephone number or the level number in a building. This module is about numbers that we want to do mathematics on. Two groups of numbers are referred to: The whole numbers are 0,1,2,3,4,5,...... (where …… means going on forever). The integers (Pronounced in‐te‐gers) are all the whole numbers plus the negative numbers, represented as: .....  5,  4,  3,  2,  1, 0, 1, 2, 3, 4, 5,....... .
